Virus evolution and emergence
Most infectious diseases arise in humans because a virus has jumped from an animal host into the human population. These include the devastating West African Ebola virus outbreak. With increased urbanisation and climate change, we can expect this to happen more frequently, but to trigger an epidemic, the disease must first evolve to be able to spread from human to human, many of these host-jumping viruses can’t do this. Dr Geoghegan’s research uses statistical and evolutionary models to discover how certain biological features of viruses can be used to accurately predict the risk of epidemics from new and emerging diseases. Her work has identified which types of viruses are likely to spread between humans and cause epidemics, and under what conditions.
